Bhagavad Gita Chapter 17.25
tad ity anabhisandhāya
phalaḿ yajña-tapaḥ-kriyāḥ
dāna-kriyāś ca vividhāḥ
kriyante mokṣa-kāńkṣibhiḥ
Translation Without desiring fruitive results, one should perform various kinds of sacrifice, penance and charity with the word tat. The purpose of such transcendental activities is to get free from material entanglement.
